IMPROVEMENT IN SULKY ROAD-SCRAPERS.

Specification forming part of Letters Patent No. 202,423, dated April16, 1878; application filed November 20, 1877.

To all whom it may concern:

Be it knownfthat I, NELsoN D. EDMOND- SON, of Crown Point, in the countyof Lake and State of Indiana, have invented a new and useful Improvementin Sulky Road-Scrapers, of which the following is a specification:

Figure 1 is a vertical longitudinal section of my improved machine,taken through the line 0000, Fig. 3. Fig. 2 is a front view of a readilycontrolled by the driver from his seat.

The invention will first be described in connection with the drawing,and then pointed out in the claims.

A are the wheels, which revolve upon the journals of the axle B. To themiddle part of the axle B is attached the rear end of the tongue 0,which is strengthened in place by the braces c. D is the scraper, whichis made in the form of a section of a hollow cylinder, with a narrowupright back, and with upright ends. The ends of the scraper D are madewith curved upper edges, to protect the curved rods E from the dirt. Theends of the curved rods E are bent inward at right angles, and areriveted or otherwise attached to the ends of the scraper D. F is aV-shaped draw-bar, which has eyes formed upon its ends, to receive andslide upon therods E, and has aloop formed upon its center, to fit intothe loop of a bracket, G, attached to the lower side of the tongue 0.The loop of the bracket G is so formed as to also receive the ring orlink g, to which the draft is applied.

This construction prevents the scraper from swinging longitudinally andthus coming in contact with the wheels A.

To the rear side of the scraper D, upon the opposite sides of, andequally distant from,

' its center, are attached eyes, to which are hinged the ends of bar orbars H. The bars H have loops formed in their ends, to receive two eyesattached to the block I, and which may be the heads of the bolts thatsecure the parts of the said block to each other and to the rod J, uponwhich it slides. The ends of the rod J are bent upward, and are attachedto the axle B and the tongue 0. To the lower side of the tongue 0 andaxle B is attached a metal plate, K, to prevent said parts from beingworn by the movements of the sliding block I. To the rear part of thesliding block I is hinged the forward end of the connectingrod L, therear end of which is bent downward and sidewise, and is pivoted to thelower end of the upright lever M. The lever M is pivoted in the rear endof the slotted bracket N, attached to the rear side of the axle B. Tothe upper end of the lever M is pivoted the rear end of theconnecting-rod O, which passes forward above the axle B, and its forwardend is pivoted to the lever P, or to a bar or lug attached to or formedupon said lever. The lever P is pivoted at its lower end to the side ofthe tongue 0, and is made with an offset, so that its upper part canswing past the drivers seat Q, the standard R of which is attached tothe rear part of the tongue 0. To the shoulder of the lever P isattached a flange or half-keeper, which overlaps the inner side of thecurved upper edge of the plate S attached to the side of the tongue 0,and along the side of which the said lever P moves. In the plate S, nearits curved upper edge, is formed a number of holes, to receive the innerend of the pin T, the outer end of which is pivoted to the lower end ofa short angle-lever, U. The lever U is pivoted at its angle to the outerangle of the lever P, and to its upper end is pivoted the lower end of arod, V, which extends upward along the side of the lever P. The upperend of the lever V is pivoted to a small hand-lever, W, which is pivotedto the lever P, and its upper end is held out by a spring interposedbetween it and the said lever P.

By this construction, by operating the lever P the rear edge of thescraper D can be raised to bring it into proper position for collectingor discharging its load, or to bring it into a horizontal position forcarrying its load from place to place.

To the ends of the scraper D are attached
